' y 1936- A. J. STOUGES SLUG CASTING MOLD Filed Nov. 2, 1935 [NV NTOR flilfi ATTORNEY Patented July 21, 1936 UNITED STATES SLUG CASTING MOLD -Anthony J. Stouges, Queens Village, N. Y assignor to Mergenthaler Linotype Company, a corporation of New York Application November 2, 1935, Serial No. 47,949'

10 Claims.

" This invention relates 'to slug casting machines -hanging face or character bearing portion is of the general organization represented in U. S. Letters Patent No. 436,532 to O. Mergenthaler, wherein a composed line of matrices is presented momentarily to one face of a slotted mold, and molten metal injected by a pump from a metal pot into the mold slot or cavity to form a type bar or slug against the line of matrices.

[In these machines, the mold slot or cavity is usually defined by four distinct parts, namely, a cap portion, a'body portion, a left-hand liner and a right-hand liner. These liners are of various thicknesses and are selectively employed to vary the dimensions of the mold slot or cavity according to the size of the slug to be cast, and to save metal in slugs of the larger sizes, such as'those of the head-letter or display variety, the cap portion of the mold is provided with a number of spaced core members or sections which terminate short of the body portion and short of the front face of the mold. A slug cast in a mold of this kind, therefore, is of the skeleton form, having a thin body portion, an overhanging face or character bearing portion, and a plurality of supporting ribs which extend from beneath the overhanging face or character bearing portion to the foot of the slug. As usual, the core members are so formed and spaced that when a slug is cast and thereafter cut to a stand ard length the ribs will provide the overhanging face or character bearing portion of the slug with the support necessary to prevent failure thereof when it is subjected to pressure.

In many instances, however, it is desirable'to cut a slug cast in a mold of this sort at an odd length, and when this is done it frequently happens thatone end of the overhanging face o'r'character bearing portion extends so far beyond a supporting rib that it fails for lack'of su'pportwhen subjected to pressure.

The present invention is intended to obviate the foregoing objection and contemplates a mold which, while adapted and arranged to cast a skeleton slug, will provide the overhanging face or character bearing portion with additional support and the necessary footage therefor without materially increasing the weight of the slug, and to this end the upper ends of the side faces of the core sections are provided with fore-and-aft grooves in which fins or vanes are cast which extend outwardly along the sides of the supporting ribs from beneath the overhanging face or character bearing portion to the foot of the slug. These fins or vanes so increase the width of the outer end of the supporting ribs that the overproperly supported regardless of where the slug is cut. Furthermore, since these fins or vanes extend from beneath the overhanging face or character bearing portion to the foot of the slug the footage necessary for the additional support is also provided.

For a more detailed description of the invention reference may be made to the accompanying drawing. In this drawing, however, the invention has been shown merely by way' of example and in preferred form, and obviously many variationsand modifications may be made therein which will still be comprised within its spirit. It is to be understood, therefore, that the invention is not' limited to any specific form or embodiment, except insofar as such limitations are specified in the appended claims.

' Referring to the drawing:

Fig. 1 is a front elevational view of a mold embodying the features of the present invention;

Fig, 2 is a sectional view taken along the line 22 of Fig. 1; i

Fig. 3 iso. sectional'view taken along the line 3-3 of Fig. hand Fig. 4 is a perspective view of a slug cast in the improved mold. 7

As shown, the mold comprises a cap portion ID, a body portion H and end liners I2 and I3 which define a mold slot or cavity M in which a slugis cast. The mold shown being of the headletter or display variety its cap portion l is provided with a series of tapered core members or sections l5. These sectionsterminate short of the body portion II to provide a longitudinal recess IS 'in which a thin body portion ll of the slug is cast and short ofthe front face of the mold to provide allongitudinal recess IS in which an overhanging face or character bearing por-' tion IQ of .the slug is cast, and they are separated by fore-and-aft recesses 20 in which transverse ribs 2| are cast to support the overhanging face or character bearing portion :19. As is usual in molds of the isortsho'wn, the core sections are so formed and spaced that when a slug is cast and thereafter cut to a standard length a transverse rib 2! will be beneath each end of the overhanging face or character bearing portion of the slug to provide the necessary support therefor.

As stated heretofore, however, it is desirable in many instances to out a slug cast in a mold of this sort at an odd length, and when this is done it frequently happens that one end of the overhanging face or character bearing portion I 9 extends so far beyond a supporting rib 2| that it failsfor lack of support when subjected to V 7 pressure.

According to the present invention, however, such molds are improved to the extent that while a skeleton slug may be castrtherein, yet the width of ;the outer end of .the supporting ribs 2| is so increased that in'theevent' the slug'is cut to lengths other than standard lengths the "over- 7 hanging face or character bearing portion 19 thereof will be properlysupported, and'to this end the upper end of the side faces of the core sections l areprovided with f ore-and-aft grooves 22 in'which fins or vanes 23 are cast which extend V i I outwardly along the sides of the supporting ribs 21 'from beneath the overhangingfaceorcharacter bearing portionl9 tothe foot of thefslugf A'slug cast in a mold'so improved, therefore,

comprises the usual thin body portion l1 and the usual/overhanging face or character bearing pore tion 19. The width-of the outer end of thetrans verse supporting ribs 2 l ,-howe,ver-, which are castin the recesses between? theopre sections 1'15 increased by the fins or Names; 23 whichproject outwardly along the sidesof -the.;rib's from,-beneath theoverhanging face or character bearing portion I9 to thefoot of the slug. The-reinforcing fins or vanes '23 thus formed provideadditional support along theedge of the overhanging face or character bearing portion I9}of the slug,

and the depth of the grooves 22 is such that the fins or vanes23 formed therein extend outwardly far enough to properly. support the overhanging face or character bearing portion J9 of the slug regardless of where the slug is cast. Also,'si nce the fins or vanes '23 extend "fore-,and-aft from beneath theoverhanging face or character bear- 7 i g portion l9, to the' foot 0f the; Slug the footage necessary for thefadditional support'is'provided.

' In the embodiment or the invention'illu'strated,

in order torkeepdown the weight of the s1ug,-the

right-hand end core sec'tion;,is not grooved and the left-hand end coresection is provided with a single groove, this being permissable since these sections are so narrow thatinthe event a slug is cast, and then cut through the recess formed by either of these sections, as here shown, theovergroove along aside face; i;

hanging face or'character bearing portion of the slug will be properly supported. a f
